Some general comments, thanks.
Please try the checkpatch script to clean up most of the errors and warnings.

Current DSPI code works as PIO mode. So please try to merge the qspi code to the current cf_spi code, and please unify the register access.

Only put the critical config in the cpu_init.c, please try to move the cs_activate and cs_deactivate to the spi driver.

Please clean up the Copyright information, Remove the Motorola information.
